The year was 2333. One hundred and eleven years had passed since the final night of human civilization. Deep beneath the ruins of an abandoned military base, a steel chamber still stood in darkness. Inside it rested a green-colored robot, asleep within a maintenance capsule. Most of its memory had been damaged.

Then, without warning, an emergency power source activated. A small light appeared in its eyes. Its metal body slowly moved, as if discovering the world for the first time.
